VINTON E. SISSON, OF CHICAGO, ILLINOIS, ASSIGNOR TO WALTER P. MURPHY, OFNEW YORK, N. Y.

RAILWAY-CAR.

Application filed April 24.

To all whom it may concern:

Be it known that I, VINTON E. Srsson, a citizen of the United States,residing at Chicage, in the county of Cook and State of Illinois, haveinvented certain new and use-' ful Improvements in Railway Cars, ofwhich the following is a specification.

My invention relates to the construction of railway cars, and moreparticularly to the trucks or running gear of the car, and the means forsupporting the car body on said trucks or running gear.

According to standard practice the body of arailway car is provided withtransverse body bolsters, one for each of the trucks, and the bolster ispivoted, in each case, usually by a center plate and king pinarrangement, to the bolster of the truck which distributes the load tothe journal boxes and axles. This method of construction involves theuse of two bolsters for each truck, both of which must be very'heavy atthe center since the entire load on the truck is carried by the portionsof the body and truck bolsters which bear one upon the other. 'As aresult the entire construction of the running gear must be relativelyheavy.

My invention provides a railway car truck which is constructed upon anentirely different principle. The car body is supported at each sidedirectly upon the journal boxes of the axle so that there is noconcentration of the weight of the car on any one point on the bodybolster. Moreover, it is possible to do away entirely with the usualtruck bolster. The supporting devices at each side of the car consist ofcoengaging members associated with the journal box and with the end ofthe body bolster so articulated that relative angular movements arepossible between the axle and the car body to give the running gearsufiicient flexibility for rounding curves.

By reducing the weight of the body bolster and of the running gear it ispossible for a freight car of ordinary size to employ twowheel'trucksinstead of the usual four-wheel trucks, thus economizing in material andfurther reducing the weight of the car.

The principal object of the invention is to provide a railway car truckof this character and more particularly to provide a two- Specificationof Letters Patent.

wheel truck, although the invention might readily be adapted to four orsix wheel trucks.

The invention consists in the novel improvements, constructions,arrangements and devices to be hereinafter described and cla med forcarrying out the above stated ob ect and such other incidental objectsWlll appear from the following description of certain vention.

In the drawings,

Figure 1 is a side elevation of a two-wheel truck constructed inaccordance with my invention. I

Fig. 2 is a fragmentary plan view of one end of the truck.

Fig. 3 is a sectional view on lone 3-3 of Fig. 1.

Fig. 4 is a sectional plan on line 44 of Fig. 1. I

Fig. 5 is a vertical sectional view on line 55 of Fig. 2.

Fig. 6 is a sectional view corresponding to Flg. 5 but illustrating adevelopment or modification of the construction shown in the first fivefigures, and

Fig. 7 is a fragmentary sectional view illustrating anothermodification.

Like characters of reference designate like parts in the several figuresof the drawings.

Referring first to Figs. 1 to 5 inclusive, 1() designates one of thewheels of the. car, 11 the axle, 12 the axle journal and 13 one of thejournal boxes. In the drawings one end only of the truck is shown. Itwill be understood that the constructions at the other side of the carwill be the same. 14 represents the flooring of the car, 15 thelongitudinal sills and 16 a body bolster which extends across the carfrom side to side.

The journal box 13 is provided preferably on opposite sides with springsupports 17 which are shown as cast integrally with the journal box,although this is not essential. On the spring supports are arrangedcoiled springs 18, 19 on which is sustained a sliding member 20 havingdepending channelshaped webs 21 which lie in vertical recesses 22 formedin the sides of the journal box. The sliding member 20 is provided witha pair of spaced, upstanding webs 23 formed preferred embodiments of thein- Q isomers at the top with bearings 24 for the outturnecl gudgeons 25of a L l-shaped hanger 2c. The hanger swings on an axis transverserespect to the car. Connected to a and. depending from the body bolsteri6 is a hanger bracket 2/? having webs 23 at right angles to the webs 23on the sliding mem ber the webs 28 being formed with bearingg recesseseulapteri to receive the ends is oi. a hanger 39 the middle portion ofwhich is formed with an upward bencl to provide a seat for engagementwith hanger 26.. The lower ends of webs 28 stand close to webs 31forming part of the vertically sliding mem- 315 her 20, the webs 31 beincurved so that, as

the hanger 26 swings orwardly or backwardly, a uniform distance will bemaintained between the lower ends of webs 28 and webs 31, or it one pairof webs 28, 31 20 are in. contact the hanger 26 may swing withoutincreasing the pressure between the hanger bracket on the car boo; andthe vertically slidable member 20. l referably the truck structure atone side of the car is connccted with the corresponding structure at theother sirle of the car. In the construction shown in the drawings a pairof angle bars 32 are secured: to the lateral rojections 33 on thesliding member 20. hese angle to bars are connected similarly to thesliding member associated with the journal box on the other siiie oi thecar.

' in Fig. 6 l have shown a development of or improvement upon the truckillustrated as in i to 5 inclusive. lln the construction shown in l to5, the hanger hraclret on the car body will be likely, in operation,bear on one side or the other upon one of the webs 31 of the slioiingmemas her 20 that is, the sliding member anti its journal box willnaturally tilt on the journal of the axle one way or the other in accoraiance with the draft on the car, and this will produce a certainamount of friction 4E tending to hamper the treeolom of movement of thehangers. overcome this ll provide shown in s, a pair of balancing figswhich are interposeol between the i G body of the car. designated 3 iinFig. 6 tension anrl compression springs. ike of the spring in each caseis secured to a disk 35 having a contering sturl 3% the clislr being pivted. to a as bracket 37 sccurecl he sizie of the body bolster 16. Theother oi? spring 341 is secured within a housing 38 which is pivoted toa bracket 39 secured to one of the lateral projections 33 on the sliclinmemso her 20, the transverse angle bar designated 32 in this figurebeing inverted for convenience in attaching bracket 39.

A. somewhat riifferent arrangement is shown in Fig. Z. The hangerbraclret assoelated with the car hotly, here clesignaterl 2?, isprovided with a pair of antitriction rollersiO aclaptecl to bear uponthe webs 31 of the sliding; member 20.

in Figs. ti and 7 the parts not specifically mentioned are the same ascorresponding parts in Figs. 1 to 5 anol are given the same referencenumerals.

@peration: The car body has a floating relation with the runnin geargiving the bo iy of the car capacity i or movement with respect to therunning gear both in the directior: of the length of the car and alsolaterally ithin certain narrow limits this relative movement between thebody and the running gear 01 the car is universal with respect todirections in a horizontal plane. As a result the axle may assume anangular position with respect to the car body when the train rounris acurve. The movements of the car body with respect to the wheels are not,however strictly in a horizontal plane. As any forward. or lateralmovement of the car body takes place through the pivotal movements ofthe hangers such longitudinal or lateral movements of the car bodyinvolve a lifting of the body from the running gear which isresisted bythe weight of the car and. these movements are therefore seli' checkinAny suriden pull on the draft gear of the car which it will beunderstood is connected with the hotly, will result in a slight forwarcimovement of the body with respect to the running gear, anti a raisingotthe car body this to the pivotal su pension thereof, This action helpsto relieve the draft gear springs of abnormal stresses in pulling andalso in bull-ling.
